Size ZeroStart Rad hose heater for '82 300D?

Gotta get a block heater tonight. What size do I need for 82 300D? Can get a Zero Start at O'Reilly for 27 bucks. I hope it's 1 1/2. Thanks all.

I have a new one in the garage. I will go measure it.

Here is what my hose measures:
OD: 1 5/8"
ID: 1 1/4"
Wall: 3/16"

The size is actually metric. You want an 1 1/2" Zerostart. I've installed two of them. They are tight but the right one.

What I meant was that the hose is not 1 1/4" and Zerostart doesn't use metric sizing (as far as I know).

My new hose measures 1 3/8" ID. But regardless of the dimension, the issue is which Zerostart fits well in the hose. Forum members have been using 1 1/2".
